ROVARTANI KÖZLEMÉNYEK LVIII 1997 pp. 147-157 New data to the knowledge on the eriophyoid fauna in Hungary (Acari: Eriophyoidea)* G. Ripka and E. de Lillo New data to the knowledge on the eriophyoid fauna in Hungary (Acari: Eriophyoidea) - Authors give a report on the results of collections made between 1990 and 1996 on street trees, in green spaces of housing estates and in botanical gardens. Eriophyoid mites were found on 84 woody plant species out of the 269 studied. A total of 85 eriophyoid species were identified. Among them, 3, 76 and 6 species of Phytoptidae, Eriophyidae and Diptilomiopidae occurred, respectively. The following 19 species were new for the Hungarian fauna: Aceria campestricola (Frauenfeld), A. ligustri (Keifer), A. marshalli (Keifer), Aculops gleditsiae (Keifer), A. rhodensis (Keifer), Aculus knowltoni Keifer, Anthocoptes striatus Ponomareva, A. transitionalis Hodgkiss, Calepitrimerus occithujae Keifer, Coptophylla lamimani (Keifer), Diptacus corni de Lillo et Fontana, Eriophyes brownei Keifer, E. burtsi Wilson et Oldfield, E. emarginatae Keifer, Rhinotergum schestovici Petanovic, Stenacis palomaris Keifer, Tegolophus califraxini (Keifer), Tegonotus pseudoobtusus Petanovic, Tetraspinus lentus Boczek. Six species: Aceria ligustri, A. marshalli, Aculus knowltoni, Anthocoptes transitionalis, Calepitrimerus occithujae and Eriophyes burtsi are new for the European fauna, too. Out of the host-plants 66 species proved to be new. The most abundant phytophagous mites are the four-legged mites. Most of them live on leaves of trees and bushes. In the Hungarian research on eriophyoid mites, after the works of Moesz (1938), Rainiss (1940) and Bálás (1941, 1948), the work of Farkas (1965, 1966) was significant. In his most comprehensive Hungarian work, Farkas (1966) gave a key and general information on the biology, feeding and damages. He confirmed the occurrence of 249 species in Hungary. In the last two decades several papers were published on gall mites attacking fruit trees and grapevines (Sántha 1981; Molnár 1987, '992; Veszelka 1992; Mezei 1994). Further information on gall mites occurring on woody ornamentals are available from the studies of Bognár and Huzián (1979), Bálás and Sáringer (1982), and Jenser (1996). MATERIALS AND METHODS Between 1990 and 1996, mite survey was made on ornamental trees and shrubs of the traffic roads, squares, green areas of housing estates, parks, botanical gardens and home gardens in all districts of Budapest. Plant samples from 269 woody plant species (minimum 5 shoots, branches or bark/plant or 25 leaves/plant) were taken in plastic bags from January to late November. During the study of the leaf surfaces made with binocular microscope, all the mites found on the plant samples were put in AGA solution or directly * Research partially supported by the Italian Ministry of University and Research in Science and Technology (MURST ex quota 40%) grant and by the Hungarian Ministry of Agriculture. Senior author collected samples, mounted specimens and partly identified genera and species. Junior author mainly identified genera and species.
